Greater transparency in quality score. To improve transparency, QualityScore in Keywords Performance and Criteria Performance will report a value of two dashes (--) when there aren’t enough impressions or clicks to accurately determine a keyword’s quality score. The HasQualityScore field introduced in v201605 will now return false for any row without a QualityScore. Finally, for criteria without a quality score, the qualityInfo attribute will no longer be returned by AdGroupCriterionServiceget and query requests.
